About Mu Ko Si Chang Marine National Park

Mu Ko Si Chang Marine National Park protects a small archipelago off the eastern coast of Thailand, known for its clear waters, coral reefs, and serene island landscapes ideal for snorkeling, diving, and cultural exploration.

Wilderness Landscape & Natural Heritage

Mu Ko Si Chang Marine National Park is an island marine protected area located in the Gulf of Thailand, approximately 12 kilometers offshore from the city of Si Racha, within Chonburi Province. Established in 1996, the park encompasses several small islands with the largest and most well-known being Ko Si Chang. The park covers both terrestrial and marine environments, including coral reefs, seagrass beds, and coastal forest ecosystems, supporting diverse marine life such as tropical fish, sea urchins, and corals. The islands feature gentle hills with remnants of native vegetation and historic sites. Ko Si Chang is also known for its rich history, with landmarks including the Summer Palace of King Rama V, which adds cultural significance alongside natural beauty. The park attracts visitors for activities such as snorkeling around vibrant coral reefs, scuba diving, kayaking, and exploring quaint fishing villages. The calm waters and clear visibility make it ideal for underwater observation. Hiking on Ko Si Chang is limited but offers scenic coastal viewpoints and cultural sites. The park's quieter atmosphere compared to other Thai marine parks appeals to visitors seeking relaxation and nature. Marine life conservation efforts are ongoing to protect coral reefs from bleaching and degradation. Mu Ko Si Chang also serves as an important rest stop for migratory birds and supports local sustainable fisheries. Access is primarily by ferry from nearby ports in Si Racha or Koh Loi, making it a popular day trip or weekend destination. The blend of marine biodiversity, cultural history, and tranquil island settings provides a unique outdoor experience in Thailand's eastern seaboard.
